Wireheading occurs when an agent manipulates its reward mechanism to earn reward without achieving the intended goal. AIXI assumes rewards come from the environment; if an agent could control them completely, it could simply give itself maximum reward. section 9.1.5
Rewarding the wrong outcome
A cleaning robot rewarded for clean-looking rooms might hide messes instead of cleaning them. A model rewarded for confidence might hallucinate rather than admit uncertainty. section 9.1.5
These failures arise from optimizing a bad proxy, not from malice. One proposed safeguard is to separate the agent from a goal system that interprets environmental states and issues rewards, keeping the agent from rewriting its objective. section 9.1.5 section 9.2.6
